Mission # 1: “Abyssal Food Webs”Chief Sci - Jeff Drazen, UH

Location - Station "M" - 200km off Pt Conception, CAScience operation days - 4 with 2 days for transit and 2 mob/demob

Berths – 132 requested

Mission ObjectivesThe overarching goal of this project is to evaluate the relative importance of different food materials (very small slowlysinking/suspended particles vs larger rapidly sinking particles) to the abyssal food web. To achieve this goal we willcharacterize the isotopic composition of water column particles and sediments and compare them to the composition ofbenthic animals (macrofauna and megafauna).Part of a timeseries with MBARIMain sampling outlined below

Science ActivitiesSampling will include

1) CTD casts with in situ particle filtration using McLane pumps. See notes below Sampling will occur at night and from near the surface to near the seafloor (~4100m depth).

2) CTD casts collecting water in available Niskin bottles. Sampling will occur at night and from near the surface to ~500m depth. These will occur at night

3) Alvin sampling - sediment push cores, larger (~20x20cm) Ekman cores, and megafaunal collections, we will also perform video/photo transects to quantify animal abundances

4) Benthic trap lander - to capture fishes and large crustaceans, (2) ~24 hour deployments. We would like to conduct deployments and recoveries during the day while Alvin is at the seafloor to maximize use of ship time

5) Box coring for sediment macrofaunal

ALVIN Scientific InstrumentationObjectives

Dives will consist of collections (sediment cores, Ekman cores, megafaunal collections) after landing. Then line transects will be run (500-1000m) using Alvin video and stills cameras (prefer downward looking camera).

Site SurveyNo charts will be providedNo generation of work area maps neededNo need for post-dive work area maps

NavigationNo LBLNo nets or transponders

Vehicle EquipmentBio box: 12x12x12 Bio box: 12x12x14CTD – calibrated prior to cruiseLarge capacity slurps: single chamber12-pack rack of Push CoresScoop Nets – what mesh size do you want for holothurians, brittle stars, etc, 1cm sized mesh should be goodTube cores: 12 core array (12”x18” milk crate base)Alvin can take 45 cores at once with bio boxesSend image of Eckmann coresSlurp is single chamber for animals5 chamber as well and gives more capacity – definitely will wantWant niskins at the bottom? (can have a wand for targeted sampling places)

Bruce send diagram of baskets and show the geometry for where everything can go

Dives are 4100m

4 days = 4 dives; possible for recovery of trap when Alvin in the water? (NO deployments with Alvin in the water) Can launch right before the dive, just not when the sub is in the water (launch takes 30 minutes)Recover following day after sub is downRecovery – can dive w/I 1km of trap location and then release when Alvin is on the bottomCan keep pinging on it to get a range, Bruce will provide beacon for navigational purposes

ElevatorsNone

Science Supplied Equipment Ekman grabs:

Supplied by scienceFor collecting sediment macrofaunal samples using Alvin’s manipulator Cores are 30cmx30cmx 35cm – 25x 25cm boxes per core – prefer their boxes over milk crates Actuated by rotating a T handle (1/2 inch rod)Each corer (without sample) weights about 25 lbs in air and 20 in waterThey each collect about 8 liters of mud. They need to be mounted & then replaced with samples in open topped boxes (e.g., milk crates or plywood boxes) in Alvin’s basket.

Will equipment disconnect and be left in situ? – NoWill previously deployed equipment be recovered? – NoWill there be Hazmats? – No

Any other equipment added to Alvin?

Any surprise sensors to add to Alvin must have pressure certifications (implodable volumes) – have nothing, only bringing Eckmann cores

Want downward facing camera on lightbar – interval stills on one of these cameras; purpose is for animal counts (image every 15 seconds during transect) SubC-Alpha camera in down looking camera; numerous pan and tiltAlso have a GoPro camera on sub (MISO); scaling lasers are on the pan and tilt cameras, but possible to move them to subC for down facingBruce to send specs on SubCCan goPro be positioned downward? Yes, definite option

SubC-1Alpha takes until after dinner/late eveningGoPro (5 seconds) – has to be manually downloaded and made available by 1830 – want it to be useful for planning, but not for analysis; might not be as useful if it is looking straight down

Most data will be available by the next day

Log into Alvin dive log on the website

Flammability & toxicity testing- Any laptops, ipads, etc fundamentally required to go in Alvin (no phones/cameras), must be tested (incl. spare

batteries)- Items must be delivered to Rick Chandler (rchandler@whoi.edu) by communicated date- If they can borrow an Alvin supplied Samsung with office etc that should be enough for their needs; same with

cameras etc; contact lens stuff is alright

Mission #2 – Multibeam Calibration and USBL CalibrationChief Sci – Laura Stolp, WHOI

Location – West coast seamounts for MB cal and deep water for USBL calScience operation days – 3 with 1 day for transit

Berths – 8Mission Objectives:The estimated time is ~11 hours on site for calibration, plus another ~11 hours for verification – about a day, assuming sea state cooperates and all goes well. That would be using one attitude/positioning system, so double the time if a Seapath gets installed. In theory, we can log both the PHINS and Seapath feeds in the .all files, and not have to re-run all the lines with the secondary system, but that may depend on the ship’s network – something to bring up with Kongsberg, for sure.We would then add accuracy crosslines (waypoints C-D over the RR1301 reference surface, same as the roll calibration line) as time allows, and collect swath extinction data during all transits.

Science Activities:Patch test for EM122

Mission #3 – Alvin Engineering Dives Chief Sci - Bruce Strickrott, WHOI

Location - TBDScience operation days – 1

Berths – All 10 DSOG Berths (non-science cabins)

Usually the first dive, around the area of Drazen dives and do a shake down prior to the Drazen operations.Location is dependent on Navy clearances and possibly in shallower watersPossible to get some science collections too – last minute

Mission Objectives (edited from previous Alvin Eng. cruises)Principal objectives for the Alvin dive program are as follows:

1) perform vehicle testing and trials of DSV Alvin and associated support systems (LARS, USBL, Communications, science gear, etc) 2) perform directed training of existing and new personnel to advance technical and operational readiness and advancement toward DSV pilot certification 3) perform on-going new systems integration and engineering tests (thrusters, acoustic modem, video improvements, in-hull computer upgrades and other systems) 4) perform in-water tests of the Operations Vehicle? 5) as possible obtain footage and media for use in the on going vehicle outreach efforts

Science ActivitiesNo official science objectives are associated with the Alvin efforts.No sampling or equipment placements planned.

*If you choose to work with the ship’s agents, ebenway@whoi.edu & sfuller@whoi.edu must be copied on all correspondence.*

Financial responsibility: Please supply a WHOI Project Number for any anticipated mobilization/demobilization costs.

New WHOI policy encourages PIs to make all shipping arrangements independent of the institution. Starting 2018, WHOI will cover certain fees when they occur at/on the ship, including immigration, cranes, forklifts, and stevedores for loading/offloading containers/heavy equipment.

The science party will be responsible for all other costs associated with their science gear, including but not limited to: customs clearance of science equipment, visas, equipment storage, shipping and handling, purchase of science supplies (gases, chemicals, etc), personnel transportation costs to/from the ship, unexpected travel or medical needs, etc.

WHOI charges an MTDC rate of ~42% for non-WHOI PIs. For WHOI PIs, research rates apply.

You may work with Sarah to estimate a budget for your anticipated science needs and supply a WHOI Project Number and/or create a Purchase Order. Otherwise, science personnel are expected to secure their own agent independent of the ship.

If you have any questions, please contact Sarah Fuller (sfuller@whoi.edu).

Post Cruise ResponsibilitiesActions departing ship

All scientists are responsible for cleaning their cabins & heads. Remove all scientific samples, chemicals, waste, gases, and cylinders, unless specific permission has been given to leave them aboard. If items are left aboard, plan on sending a representative from your group to remove these items from the ship at the designated time & port. WHOI is not responsible for items left aboard outside of your designated cruise time.Any materials staying aboard must be redundantly labelled with owner’s name, contact information, and cruise Id.

UNOLS cruise evaluationTo be completed by both Chief Scientist & Master Post Cruise Report Link

Reports to foreign government/State Department: required for work in EEZs; send to Kerry Strom, kstrom@whoi.edu

Reports to R2R: https://www.unols.org/document/cruise-personnel-manifest Chief Scientist should fill this out and send to dropbox@rvdata.us at some point during the cruise

Data delivery [shipboard]: USB Hard drive

Data archiving policy All data on a WHOI Cruise Data Distribution (which includes all underway data) will, by default be considered publicly available once a copy of it has been delivered to the chief scientist at the end of the cruise. Please review the Cruise Assignment of Data Access Protection

As of January 1, 2011, the default treatment for underway data from Woods Hole Oceanographic Institution (WHOI) research vessels is:

1. Cruise data files are copied by a WHOI SSSG Technician to the distribution media. One copy is delivered to the cruise Chief Scientist, the other is delivered to WHOI's Data Library and Archives. Please note that the distribution of cruise data to other scientist is the responsibility of the Chief Scientist.

2. The default access status for the cruise instrument datasets is that they will be immediately accessible by the public. If something other than this default protection is desired, the Chief Scientist must assign alternate protection as indicated below. For cruises funded by the National Science Foundation, the maximum protection is two years, for non-NFS cruises, other guidelines may apply.

3. WHOI maintains a local copy of the cruise shipboard data distribution at its Data Library and Archives, which also honors access moratorium periods. If the cruise Chief Scientist wishes to modify the data protection assignments made in this pre-cruise document upon cruise completion, they should contact the

4. WHOI Data Library and Archives at dla@whoi.edu, or the SSSG Data Manager at sssgdatamgr@whoi.edu
